SMOKING PIPE Filed Feb. 18, 1937 Patented Oct. 25, 1938 UNITED STATESVPATENTQ'OFFICEY 2 Claims.

This invention relates to smoking pipes, the primary object of theinvention being to provide means for connecting the stem to the bowl ofthe pipe, in such a way that the stem may flex with respect to the bowl,thereby insuring against the stem becoming broken when pressure isexerted at either end of the pipe, or at the point of connection betweenthe stem and bowl.

Another important object of the invention is to provide means forinsuring an air-tight connection between the stem and bowl of the pipe,the means also acting to prevent loss of the pipe from the pocket of theuser.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein described, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing:

Figure 1 is a longitudinal sectional view through a pipe constructed inaccordance with the invention.

Figure 2 is a plan view thereof.

Figure 3 is a sectional view taken on line 33 of Figure 1. I

Referring to the drawing in detail, the reference character 5 designatesthe bowl of a smoking pipe, which is provided with the usual bore 6, inwhich the metal tube I5 is positioned.

The reference character I designates the stem of the pipe, which isprovided with the usual bore 8, through which smoke is drawn through thestem. Metal tube I6 is positioned in the bore 8, the tubes 15 and I6providing the lining for the bore of the pipe.

The reference character 9 designates a pin which extends through thestem, and to which one end of the coiled spring I is connected, thecoiled spring [0 being of a length to extend to a point adjacent to thebottom of the bowl of the pipe, as clearly shown by Figure 1 of thedrawing.

A pin indicated by the reference character ll, extends through theextension of the bowl 5, and is adapted to cooperate with the coiledspring l0,

when the pipe stem is rotated in positioning the pipe stem in the bowl.It will be seen that due to this construction, as the stem is rotated,the convolutions of the spring contacting with the pin I l will act todraw the stem towards the bowl, or move the stem away from thebow1,'according to the direction of rotation of the stem.

In the construction of the pipe, the pipe 'is formed in such a way thatthe inner end of the stem 1 will lie in spaced relation with the end of10 theextension of the bowl 5, the space between the end of the stem 1and extension of the bowl 5 being filled by the washers I2, the washersbeing tapered, so that the washer nearest to the extension of the bowl5, will fit into the end of the bore of the extension, and the extensionof the adjacent washer will fit into the tapered opening of thecooperating washer,insuring an air-tight connec-. tion between thestemand bowl of the pipe.

From the foregoing it will be seen that due to the construction shownand described, the stem of the pipe may bend laterally withoutdanger ofbreaking the stem from the bowl of the pipe.

It will further be seen that by rotating the stem in one direction, thecoiled spring maybe fed over the pin I I, in such a way as to permit thestem 1 to be disconnected from the bowl to facilitate cleaning. I

Having thus described the invention, what is v claimed is:

l. A smokers pipe comprising a bowl section and a stem section, saidsections having bores, tapered washers fitted together, the tapered endof one washer extending into the bore of the pipe section, and yieldablemeans connecting the sections.

2. A smokers pipe comprising a bowl section and a stem section havingbores, washers between the sections holding the sections" spaced apart,a

coiled spring secured within the bore of one sec- 40 tion, a pinextending through the bore of the ad-. jacent section, said coiledspring adapted to engage the pin, yieldably connecting the sections, andsaid coiled spring adapted to draw the sections together when onesection is rotated with respect to the adjacentsection, in apredetermined direction.
